looks like hack to me. why not one and not three? can we use more reliable way here, for example events?

[kristina-fefelova]

oh, I used same hack in old chat, it is because of <Component..>. and the more they are nested, the longer we have to wait ticks.

need to find a better solution

[rostislavnagimov]

I was making that based on the existing chat components says the "one tick is not enough to load chat messages"

Till this moment all other ways was not really working for me (tested something like 5-7 other solutions)

• Ensure that the 'tabId' parameter's type matches t._id. If 'tabId' is a Ref, comparing it directly to an identifier might lead to unexpected behavior; consider using 'tabId._id' or updating the parameter type to a string.

const tab = tabs.find(t => t._id === tabId);

plugins/workbench-resources/src/components/Workbench.svelte:297

• Verify that the value of 'tabId' (retrieved from $tabIdStore) is of the same type as t._id. If it is intended to be a string, ensure that there is no unintended wrapping or type mismatch that might cause the comparison to fail.

const tab = get(tabsStore).find((t) => t._id === tabId);
